Little spacial multi-angle high pulling torque bolts assemblies device

Technical field

The utility model relates to bolt clamp device, be specially a kind of can be for the multi-angle in the little space big specification bolt the bolt clamp device of pretightning force is provided.

Background technology

Bolts assemblies device commonly used on the present market, according to different operating positions and requirement, can be divided into many types, no matter but be manually, hydraulic pressure, mechanically all have certain deficiency: the operating space of fluid pressure type requires high, complicated operation needs external hydraulic means; Manual and mechanical type also requires certain operating space and can't provide to do enough big moment of torsion, when being applied to the big specification bolt of various assemblings, all its space that can utilize or moment of torsion all there is certain requirement, make that various tool in use needs to change continually, influenced operating efficiency, it is very inconvenient to use.

Some spanners can't easily be operated for some dead angles or little area of space simultaneously, and the zone of certain angle is perhaps arranged, and can't provide enough big moment of torsion to finish the work.

The utility model content

The technical problem that the utility model solved is to provide little spacial multi-angle high pulling torque bolts assemblies device, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solved realizes by the following technical solutions:

Little spacial multi-angle high pulling torque bolts assemblies device mainly comprises driving handle, support arm A, gear-box, support arm B, support arm C, connector, conical gear, ball, conical tooth roller box and supports the arm of force and multi-functional driving head.

Conical tooth roller box of the present utility model is an agent structure of the present utility model, is a body structure, and inside mainly comprises two angular wheels, and angular wheel can multi-angle distribute, and is the transmit force structure of this device, and the below of each angular wheel all is distributed with ball.One side of conical tooth roller box is for supporting the arm of force, in order to stable under the duty that an extraneous support force keeps the conical tooth roller box to be provided.

Conical tooth roller box of the present utility model below can connect multi-functional driving head, can select different joints according to different requirements.

Conical tooth roller box of the present utility model rear connects gear-box by connector, wherein connector is a class bearing torque structure that can reverse, be used for carrying moment of torsion, lower gearbox portion is support arm B and support arm C, wherein support arm B is shorter, the bottom connects support arm C, but both multi-angles distributions are carried out device by the supports outer structure and fixed.

The gear-box rear portion connects driving handle and support arm A, and the both is a rod shaped structure, and driving handle is a manual control mechanism, can provide moment of torsion to carry out operation more easily by support arm A.

Beneficial effect: the utility model is simple in structure, and is easy to use, can do the operation of multi-angle high pulling torque in little space, improved operating efficiency, and safe and reliable.

Description of drawings

Fig. 1 the utility model schematic diagram.

Wherein: driving handle 1, support arm A 2, gear-box 3, support arm C 4, support arm B 5, connector 6, conical gear 7, ball 8, conical tooth roller box 9, the support arm of force 10, multi-functional driving head 11.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

A kind of little space high pulling torque bolts assemblies device that is applicable to referring to Fig. 1, can apply an active force at driving handle 1 end, can assist by support arm A 2 when applying this active force, in this process, need to utilize 4 pairs of gear-boxes 3 of support arm B 5 and support arm C to fix.

Behind rotating drive handle 1, can carry out the relative amplification of power by gear-box 3, make its purpose that reaches high pulling torque output, after amplification, by connector 6 active force is transported in the conical tooth roller box 9, realize the amplification once more and the output of moment of torsion by the connection of two conical gears 7, and be transported to the assigned work position, in this process, ball 8 can reduce the friction of conical gear 7 in rotation process, the consumption of minimizing power in this process, can come the fixing of generator by supporting the arm of force 10.

Be connected with multi-functional driving head 11 in conical gear 7 bottoms, output mechanism that can outer relay by being fixed on the edge of conical tooth roller box 9, makes high pulling torque be able to final realization, thereby reaches the purpose of loosening or pretension associated mechanisms.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
